Australian Football General Sizes
Footy sizes are delegated primarily on the basis of the player’s age and specifications are described in relation to the lengthwise circumference of the ball and the transverse circumference (around the middle of the ball).
|Size||Age Group||Circumference (inches (cm))|
|1||5-8 (Auskick)||17.7 (45)||24.4 (62)|
|2||9-11||18.9 (48)||25.2 (64)|
|3||12-13||19.7 (50)||26.4 (67)|
|4||14-15 (preferred size for adult women)||20.5 (52)||27.6 (70)|
|5||16+||21.3 (54)||28.3 (72)|
Not all footballs are made equal with there being a slight variance between each one. Smaller novel footies in AFL club colors are often available and come in either 16 or 20cm sizes. This refers to the length of the footy from end-to-end. Therefore the lengthwise circumference is smaller than size 1.
